LEGO MINDSTORMS Haunted House Community Building Challenge

Did you know that many haunted houses and haunted amusement park rides use animatronic robotics? That creepy Dracula that pops up out of the coffin was most likely triggered by a motion or touch sensor, and has motors and gears hidden inside to control its movement.
Halloween is just around the corner and the LEGO MINDSTORMS crew wants you to celebrate by creating some Haunted House robots!
You can make an animatronic Halloween character, or an entire robotic controlled Haunted House! Will you make a bat that flies on a string? A pop-up coffin? A dancing ghost? How about a band of scary spooks called the “boo crew?”
Deadline: November 1, 2014
